📜  计算四面体面积的程序

📅  最后修改于: 2021-05-28 04:42:39             🧑  作者: Mango

四面体只是具有三角形底面的金字塔。它是一个具有四个三角形面,三个侧面或侧面,一个在底部或底部以及四个顶点或拐角的固体对象。如果面都是全等边三角形,则将四面体称为正则面。
四面体的面积可以使用以下公式找到:

Area = sqrt(3)*(side*side)

例子 :

Input : side = 3
Output : 15.5885

Input : side = 20
Output : 692.82

    int side=3;
    cout<< "Area of Tetrahedron ="
        << area_of_tetrahedron(side);
